War of the Wolf by Bernard Cornwell
Uhtred of Bebbanburg has won back his ancestral home but, threatened from all sides by enemies both old and new, he doesn’t have long to enjoy the victory. In Mercia, rebellion is in the air as King Edward tries to seize control. In Wessex, rival parties scramble to settle on the identity of the next king. And across the country invading Norsemen continue their relentless incursion, ever hungry for land.
